Louis Erard x Vianney Halter II: A Collaboration of Genius and Craft

Louis Erard and Vianney Halter unveil their second collaboration. Both independent companies share philosophies that complement each other, which is what makes this watch so special. Louis Erard showcases its expertise in regulator designs, and without a doubt, they are the most famous company in this kind of high-precision watch. We have already shared the detailed history of regulator watches in this previous article.

The genius watchmaker Vianney Halter infuses his iconic design elements into the watch, drawing inspiration from science fiction and space. By merging these influences with his exceptional craftsmanship, he creates a truly distinctive timepiece. The Louis Erard Régulateur’s design seamlessly complements Halter’s signature split-time subdials and the uniquely crafted bezel, adding a futuristic touch to the watch.

Introducing Moritz Grossmann Unveils Two Limited Edition Heritage Power Reserve Watches

Vibrant Dial Colors in Collaboration with U.S. Retailer Exquisite Timepieces

Moritz Grossmann, in partnership with its U.S. retailer Exquisite Timepieces, based in Florida, has unveiled an exclusive limited edition model: the POWER RESERVE Steel Limited Edition. This release features two striking dial variants in mint green and light blue. These vibrant colors enhance the watch's aesthetic appeal and legibility. Known for its strong relationships with retail partners, Moritz Grossmann frequently honors them with special editions. Recently, the brand commemorated the 70th anniversary of its Singapore retailer with a unique release, and now it celebrates its partnership in the U.S. with this remarkable timepiece.

Both versions of the POWER RESERVE Steel Limited Edition are housed in a polished stainless steel case, measuring 41 mm in diameter and 11.65 mm in height. The classic round shape is accentuated by slim bezels, maintaining the timeless elegance of the design. A sapphire crystal protects the dial, while the case offers water resistance up to 30 meters.


A standout feature is the crown and pusher positioned at 4 o’clock—hallmarks of Moritz Grossmann's innovative mechanisms. These elements contribute to the watch's functionality while maintaining its refined appearance.

At the heart of the watch lies the Grossmann manual winder with pusher, featuring a sophisticated hand-setting mechanism. This system addresses two common challenges: preventing foreign particles from entering during adjustments and avoiding unintentional hand movement when the crown is pushed back.


The mechanism transitions to hand-setting mode with a simple pull of the crown, simultaneously stopping the movement. The crown then returns to its original position, allowing precise hand adjustments. The movement is restarted via the pusher, resetting the mechanism to winding mode without further crown manipulation.


The solid silver base dial, available in mint green or light blue, is meticulously colored to perfection. A linear power reserve indicator is positioned at 12 o’clock, directly beneath the Moritz Grossmann logo. Manually crafted steel hands, annealed in blue, harmonize beautifully with the vibrant dials and matching blue Arabic numerals. Additional features include a small seconds subdial at 6 o’clock and a minute rail track encircling the dial.

The sapphire crystal case back reveals the intricately finished calibre 100.2, an evolution of the calibre 100.1, the movement used in the timepiece celebrating the brand’s 16th anniversary,  featured in a limited-edition enamel watch.

This manual-winding movement incorporates a differential gear for the power reserve display, operates at 18,000 vibrations per hour (2.5 Hz), and provides a 42-hour power reserve.

Limited to just 10 pieces per dial variant, these watches come with hand-stitched black buffalo leather straps, featuring stitching in mint green or light blue to complement the dial colors. Each watch is priced at USD 35,900, approximately AED 132,000
